There's no shortage of podcasts about David Lynch's influential series, but with the Netflix revival on its way, the "Twin Peaks Log" may be one of the best places to peek behind the strange curtains of the red room.
One of the hosts (Mark) is a long time fan of the series, while the other (Rebecca) is watching for the first time. Between the two, they have a thoughtful analysis of each episode, but always find time to stop and enjoy the surreal dreamscape that is Twin Peaks.
Both hosts are active on other pop-culture podcasts (United Nations of Horror, The Good, the Bad, & the Odd, etc.) and each has written extensively about the horror and science fiction, and their extensive scholarship shows in all aspects of the production.
Stongly recommended!
